IMPROVEMENT IN BRAIDINGMACHINES.

Specification forming part of Letters Patent No. 160,198, dated February23, 1875; applica'ion filed December 5, 1874.

To all whom it may concern:

Beit known that I, FRIEDRICH WILHELM HUPPELSBERG, of Brooklyn, E. D., inthe county of Kings and State of New York, have invented a certain newand Improved Braiding-Machine, of which the following is a specication:

This invention is illustrated in the accompanying drawing, in which-Figure 1 represents a transverse vertical section. Fig. 2 is ahorizontal section in the plane a: x, Fig. l. Fig. 3 is a plan or topView, partly in section. Figs. 4, 5, and 6 arel diagrams, which will bereferred to hereinafter.

Similar letters indicate corresponding parts.

This invention relates to a braiding-machine in which la number of jacksor spindles containing the bobbins are used, which receive their motion.by notched disks or carriers, and which move in an 8shaped race-course.

My invention consists in combining with an even number of jacks twonotched disks oi unequal diameters and an uneven number of notches, thenumber of notches in the large disk being two more than that in thesmall disk, with or without intermediate notched disks, in such a mannerthat at braids can be produced from an even number of strands, and theproduct obtained be materially improved.

In the drawing, the letter A designates the top plate of mybraiding-machine, which is provided with an 8-shaped guide-slot orracecourse, a b, for the jacks B. The circles a b, which form theS-shaped race-course, are of unequal diameter, and in the center of thecircle a is secured a xed axle, c, on which is fitted a tube, d, whichcarries at its upper end a disk, G, and at its lower end a cog-wheel, D.In the center of the circle b is a fixed axle, c, on which is fitted atube, f, that carries at its upper end a disk, E, and at its lower end acog-Wheel,F. The pitch circle of the cog-wheel D is equal to the meandiameter of the circle a, and the pitch circle of the cog-wheel F equalto the mean diameter of the circle b, while the diameter of the disks Oand E are such that they revolve in close contact with each other withthe same circumferential velocity. The number of jacks to be used in mymachine is an even numberfor instance, eight, or

twelve, or thirty, or more-and if' the number of the jacks is eight thedisk C is provided with seven, and the disk E with nine, notches in itscircumference, or, it' only two disks are used, and the number of jacksis equal to fn, the large disk E has n+1, and the small disk O u-lnotches, the number of notches in the large disk being two more thanthat in the small disk; but if the disks O E are used, together with aseries of intermediate disks, as shown in Fig. 4, the number oi notchesin the large disk E maybe seven, thatin the small disk five, and that inthe four in termediate disks four in each, and a machine is obtainedcapable of carrying w=14 jacks.

The jacks B are provided with iianges g h, which are connected by narrowstrips c', the flanges g being situated close above, and the anges hclose below, the plate A, while the strips z' extend through and move inthe 8- shaped guide-slot a b. From the lower flan ges h of the jacksextend feet j into the notches of the disks G E. When the machine is setin motion the jacks move in the direction of the arrows marked on the8-shaped guidegroove in Fig. 3, and each jack, when it reaches thejunction of the eight, passes from one circle to the other.

I am aware that braiding-machines of a similar construction to mine havebeen known for a long time, but in all such braiding-machines intendedfor flat braiding which I have ever seen the disks E and O are made ofequal diameter, and with the same but with an uneven number of notches,for if the disks E and O are made of the same diameter, and an evennumber of notches is used, (intended to work with an even numberofjacks,) the work produced becomes thinner on one edge than ou theother.

In order to illustrate the impossibility of using, in a braiding-machinefor making flat braids, two disks, O and E, of equal diameter, and of aneven number of jacks, I have shown, in Fig. 5, two such disks, each witheight notches and capable of carrying eight jacks. If these jacks arearranged as shown in said ligure the jacks 1 and 2 follow each other inthe same disk C, and, consequently, the threads carried by these jacksare not braided-they lie dat against each other. It' the disks areturned inthe opposite direction the jacks 1 and 3 will follow each otherin the same manner, and if an attempt is made to arrange the jacksdifferently in the disks those of the disks E will either run againstthose of the disk C or the threads will not be properly braided. If thedisks C and E are constructed with equal diameters, and with an unevennumber of jacks, (see Fig. 6,) as usually practiced in machines formaking Hat braids, the disk on the Vside Where the threads are untwistedin braiding contains a smaller number of jacks than that on the otherside, and one edge of the braid becomes thinner than the other.

For braids of one color the old style of machines Work perfectly Well,but if a tlat braid is to be produced ot' two different colorsforinstance, White and black-it is desirable to use the same number ofWhite and black strands, and consequently an even number of jacks mustbe employed. For such Work my improvement is of great advantage.

What I claim as new, and desire to secure by Letters Patent, is

In a braiding machine, the combination, With an even number of jacks orbobbins, of two disks, E C, of unequal diameter, each disk beingprovided With an uneven number of notches, the number of notches in thelarge disk being two more than that in the small disk, said disks beingmade to revolve at the same circumferential velocity With or Withoutintermediate disks, substantially as and for the purpose shown anddescribed.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 30th day of November, 1874.
